I'm using InDesign 5.5 on a Mac (Mac OS X 10.8).
I have created a book document contaiing about 30 chapter files. All the chapter files are synchronized.
Now I want to reformat the entire book. It is currently 8.5 x 11; I want to reformat it to 5.5 x 8.5. It is also double-spaced; now I want it to be single-spaced. Is there a way to make these changes (paragraph styles and repagination) automatically in one fell swoop, or am I going to have to go in and tweak, or re-place, each of the component files individually?
